Is truth actually truth? Absolute truth is impossible. @Devans99
"If you have a proposition X and also propositions Y and ~Y then you can prove X is absolutely false if you can show:
X AND Y = false
X AND ~Y = false
Then by exhaustion of the probability space, we can absolutely conclude that X is false. Note that we have not used any axioms to prove that X is false so it is 'absolute knowledge'."
Makes sense to me, but i'm sure you know if you were in a control tower at an airport even though you are required to make good judgements, those judgements must be made quickly and fairly accurately in a short period of time, in other words out in public there are alot of variables.
